The vLoc3-DM is used to precisely locate pipelines and assist in evaluating pipe coating defects. The system can be used on either transmission or distribution systems. A complete ACVG survey can be undertaken using the vLoc3-DM and plug-in A-frame. The display on the vLoc3-DM has been configured specifically for pipeline evaluation. Data can be graphed in real-time on the receiver while still on site. The walk back feature highlights the operator’s position on the graph allowing them to return to the point of interest where further evaluation or an ACVG, A-frame survey can be undertaken.

With two sets of 3D antennas, signal distortion is easily detected and displayed on the bright full-color display. The vLoc3-DM introduces new locate perspective screens of Vector Locate for fully automatic non-walk over locating, Transverse Graph showing both peak and null simultaneously providing an immediate measurement of signal distortion, and Plan View showing the relative orientation of the cable at any angle. Visual and mechanical vibration alerts can also be configured by the user providing warnings for shallow depth, overload, overhead cables, and excessive swinging.

The 150-watt Loc-150Tx DM Transmitter typically applies the locate signal by connecting to the pipe at CP stations and test posts. The transmitter is designed to be powered from CP stations, AC or external batteries. Two rotary/push control knobs provide access to frequency selection, output level, menu information and active/standby modes. This transmitter is supplied with a direct connection lead, DC input lead and AC mains lead.
